WASHINGTON (AP) — An environmental group is spending almost $1 million to criticize a likely Republican Senate nominee as beholden to billionaire industrialists and "too extreme for Colorado."
The League of Conservation Voters is running an ad against congressman Cory Gardner, who is likely to face Democratic Sen. Mark Udall in November. In the ad, the environmental group says Gardner voted to keep giving billions in special taxpayer-funded subsidies to oil companies such as those owned by Charles and David Koch.
A Koch-backed group, Americans for Prosperity, is already on the air with an ad criticizing Udall's support for the national health care law.
The League of Conservation Voters says the Kochs are funding "a million-dollar smear campaign" to protect "billions for big oil."
Democrats and their allies have aggressively criticized the Kochs.
